Renewed April 8, 1933' Claims.

This invention relates to a roll supporting device used in connection with the printing presses. The principal objects of the invention are to provide a simple and convenient means for shift- 5 ing the spiders or other supporting devices for the rolls so as to accommodate rolls of different widths and to provide the spider supporting shaft with means by which the spiders can be shifted very readily along the shaft.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to drawings, in which Fig. 1 is a side view of a roll supporting reel showing a preferred embodiment of this invention applied thereto;

Fig. 2 is a sectional view on the line 2-2 showing the shaft in section and the reel in elevation; Fig. 3 is an enlarged view similar to Fig. l

the accompanying 2; showing the application of the roll shifting means;

Fig. 4 is a plan of the spider barring key;

Fig. 5 is an elevation thereof, as indicated by the arrow 5 in Fig. 4, partly in section;

' Fig. 6 is a plan of the spider clamping shoe as indicated by the arrow 6 in Fig. 7;

Fig. '7 is an elevation of the spider clamp shoe;

Fig. 8 is a sectional View through the shaft, spider and clamp shoe, and

Fig. 9 is an edge detailed lever.

The shaft 1 of the reel is supported between two pedestals 2, which are fixed in position. The shaft is adapted to be rotated through a worm wheel 4.- by a motor and worm, not shown, or in any other desired way.

The reel proper consists of the shaft 1 and two spiders 5 mounted thereon. The shaft is supported by pedestals 2 and is rotated by a motor,

40 not shown, operating through a worm wheel 4. The spiders carry spindles 6 for supporting the paper rolls. Three arm spiders are shown for supporting three rolls but the invention is not limited to that number of rolls.

The spiders 5 are held rigidly in position on the shaft 1 by a longitudinal key '7 fitting into a supplementary keyway in the shaft 1 and the spiders. The key 7 is fitted the entire length of the shaft 1 between the pedestals 2 and is secured to the shaft by set-screws 11. This key carries a series of barring or fulcrum elements,

preferably in the form of cylindrical holes 12.

To secure the key 7 to the spider a clamp shoe 8 is employed. This is provided with two clamp ing screws 9 which are screwed up to engagethe 30; view of the barring right the barring lever clamp shoe and hold that and the key fixed with respect to the spider. The clamp shoe 8 carries a pilot projection 10 extending into a recess in the spider 5 so that the longitudinalsliding of the spider carries the clamp shoe along with it.

As so far described, the spiders are fixed to the shaft but when it is desired to shift the spiders one way or the other, the screws 9 are loosened so that the spider, together with the clamp shoe, is free to slide along the shaft with the barring key, which is fixed to the shaft. For the purpose of moving the spiders, a barring lever 14 is employed having a pin 13 secured thereto and projecting from both sides. Any other fulcrum element can be used cooperating with whatever provisions are used on the key. This pin 13 is placed in one of the barring holes 12 andthe end 15 of the lever engages the hub of the spider.

If it is desired to move the spider to the left, as shown in Fig. 3, the barring lever is swung out at 15 to the right as indicated by the arrow in full lines in Fig. 3. This moves the spider to the left. If it is desired to move the spider to the is put in the dotted line position shown in Fig. 3 and moved over so that the pin 13 enters the barring holes 12. Now the handle is moved to the left as indicated by the dotted arrow to push the spider to the right. In some cases the lever will be used the other way around so that the short end will bear away from the spider. The holes 12 in the key '7 are placed close enough together so that the pin 13 can be placed in successive holes to move the spider easily.

It will be obvious that any setting of either of the two spiders can be accomplished simply by loosening the clamping screws 9 and barring the spider over in either direction as just described. Then the clamping screws 9 are clamped to hold it there.

This constitutes a simple and powerful device for easily shifting the spiders on a paper roll reel for accommodating rolls of different widths. There are no loose parts except the lever '14. It is often necessary to change the spiders, sometimes from one day to the next, or even between editions, to change the make-up of the product by changing the number of rolls or by using a different width roll to give the desired result. This, invention accomplishes this purpose in a very simple manner.

Although I have illustrated and described only one form of the invention I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited in this respect but what I do claim is:-

1. In a paper roll support, the combination of a supporting shaft having a series of spaced fulcrum elements therealong, a spider located on the shaft and capable of being moved along the shaft, and a lever having a complementary fulcrum element adapted to cooperate with any one of said fulcrum provisions to pivot the lever and adapted to bear against the spider to move it along the shaft.

2. In a paper roll supporiathe combination of a supporting shaft having a series of fulcrum holes therealong, a spider located on the shaft and capable of being loosened so as to move along the shaft, and a lever having a pin thereon adapted to enter any of said holes and adapted to bear against the spider to move it along the shaft.

7 3. In a paper roll support, the combination of a shaft, a pair of spiders on the shaft for supporting the paper rolls, the shaft having a series of holes extending substantially from one end to the other, a clamp shoe by which the spider can be clamped in any position on the shaft in which it may be placed, means for releasing said clamp shoe to allow the spider to be moved along the shaft, and means adapted to be engaged in any of said holes for cooperating with the spider to push the spider along the shaft.

4. In a printing press supply roll reel, the combination of a shaft having a longitudinal groove therein, a key fixed in said groove, said key having a series of elements adapted to cooperate with a device for moving the spiders of the reel individually along the shaft, and means for clamping the spider to the shaft.

5. In a paper roll support, the combination of a shaft, a key extending along the shaft and having barring holes therein at short distances apart, a pair of spiders for supporting the rolls, means for clamping said spiders to the shaft, said means being releasable, and a barring lever having a pin adapted to be inserted in one of said holes in position to bring the short end of the lever against the hub of the spider, whereby the spider may be moved along the shaft.
